* I should like to say “the points of inflexion,” but Mr. Fowler’s definition does not allow me; may I suggest that to be consistent Mr. Fowler ought to define a tangent as a line that meets a curve without crossing it!

Readers should be warned that writers differ in the convention governing the sign of torsion, and that opinion is settling down in favour of the opposite rule to that used in the tract.
